Secondary title: Experimental infiltration measurements on different soil types with mini disk infiltrometer
Secondary abstract: Infiltration is the process of water entering the soil. It is one of the most important processes of the hydrological cycle. The rate of infiltration is the maximum velocity at which water enters the soil an is expresed in mm/h. For the assessment of the rate we can use physically based or empirical methods and also infiltration indexes. Infiltration can also be measured. Instruments are called infiltrometers. They can be devided in to three groups: ring (cylinder), tension and sprinkler infiltrometers. Mini disk infiltrometer is a tension infiltrometer. The objective of this study is to theoretically describe the process of infiltration and factors it is dependent on, to give appropriate management options for improving soil properties, to evaluate the usefulness of mini disk infiltrometer and compare it with standard double ring infiltrometer. Series of measurements were made with mini disk infiltrometer for three different soil types and two different most common land uses on the Glinščica watershed. Measurements were made on and under the soil surface, respectively. Also series of measurements with the standard double ring infiltrometer were made to verify the MDI infiltrometer results. Results of measurements were verified and compared with the results of other similar studies.

Abstract (ePrints): Infiltracija je proces vstopanja vode v tla skozi površinski sloj zemljine in predstavlja enega izmed najpomembnejših procesov hidrološkega kroga. Stopnja infiltracije je hitrost, s katero voda vstopa v tla in jo običajno izražamo v mm/h. Za oceno stopnje infiltracije se lahko poslužujemo fizikalnih in empiričnih metod ter infiltracijskih indeksov. Meritve na terenu izvajamo z infiltrometri. Instrumente delimo v tri skupine in sicer na cilindrične, tlačne in razpršilne infiltrometre. Mini disk infiltrometer spada v skupino tlačnih infiltrometrov. Cilji naloge so podrobneje opisati proces infiltracije, spoznati vplivne dejavnike in opredeliti ustrezne ukrepe za izboljšanje infiltracijske sposobnosti tal ter praktično preveriti uporabnost mini disk infiltrometra ter ga primerjati s standardiziranim dvojnim obročem. Na eksperimentalnem porečju Glinščice so bile z mini disk infiltrometrom izvedene meritve na treh različnih tipih tal ter na dveh najpogostejših rabah tal. Vsakič so bile meritve izvedene v nivoju tal in v vkopu. Za kontrolo so bile na istih tipih tal izvedene še meritve s standardiziranim dvojnim obročem. Rezultati meritev so medsebojno primerjani ter ovrednoteni s primerjavo vrednosti rezultatov v tuji strokovni literaturi.
